Prateek Grand Begonia: RERA compliance doesn't mean timely delivery

Since last year I've been tracking Ghaziabad properties, and Prateek Grand Begonia Phase I looks decent on paper. But honestly, I feel builder RERA promises are just paper-work, not actual delivery guarantee. Is it just me, or Prateek Builders ka track record for timely possession thoda shaky hai? Will they actually deliver this one on time? Price bhi ₹1.29 Cr se start hai, kaafi high lag raha for an ongoing project. Has anyone seen real capital appreciation since launch? Ya bus brochures mein hi sab kuch achha lagta hai? Change my mind.
